[linux-audio-dev] recording, sample rate problem

by Turos Laszlo

Hi I'm trying to write a soundrecorder application under linux. I have Redhat 7.2 with kernel 2.4. Playing sound on my soundcard works fine,but I'm having problems recording. I was using GNOME Sound recorder 1.2.3 to record sound but it seems that it can only record sound at a 48000 Hz sampling rate,but playing back the recorded sound it is a noise. I wrote a little program myself and I reached the same conclusion that I can not set other sampling rate than 48000. My soundcard under Windows records good sound with other sampling rates. I have my soundcard on my VIA motherboard. In my harware Browser looks like this: Manufacturer: VIA Technologies Driver: via82cxxx_audio Can anybody give me a hint? Best regards Laci

[linux-audio-dev] midi 'resolution'

by Lukas Degener

Hi list, maybe someone can explain this to me (me==stupid :-) ) In a system/application, that recieves external midi data of any kind, is there anything one can assume about _when_ some midi data is recieved? i mean, with audio data, you have the buffer size of the dac/adc, which (together with sampling rate) enforces some kind of "global clock" impulse/trigger in your system. Is there anything similar with midi data? Still waiting for enlightenment, Lukas ps: oh and btw, i would like to say another BIG THANK YOU to Frank and Matthias and all the others involved in making the lad conference possible. i had a realy great time there. Hope we can have something like this again in not to far future.

Re: [linux-audio-dev] Echo Darla/Gina/Layla/... on Linux

by Ranjit Singh

Sorry not to respond sooner, can't work out the Konqueror history thing= it doesn't even sort by date, for crying out loud.. ;) I downloaded the Event code as well, although not sure where it is on the machines, since I've converted eveything to Linux. Since the code was put out publically, can't we just put it up on a project site (eg sourceforge, freshmeat) as a central resource? >From what I read we have: 2 x20 bit Layla (David Olofson and Lamar Owen) Darla 24 and Gina 20 (Brad Arant) and I have a Darla 20 bit, one of the originals ;) so between us I reckon we have enough hardware to test a generic driver, and also enough code knowledge (from your comments) to get something together. I don't know loads of Intel TBH, my experience is: 6502, Z80, 68000, ARM, and i386+ only in the last year or so. What do you reckon about sorting a project out between us? I don't know loads of Linux module stuff either- Brad and David it sounds like you're the men on that. I have done quite a bit of coding, and would love to try and keep the project on track, since you guys know the setting better. Lamar, since you're on Internet Radio and that, maybe you'd like to do the testing from an engineer's perspective? (ie with stability and throughput as your main goals.) Do you have any coding experience? Let me know what you reckon; it's really cool to hear from other coders who like a nice sound from their boxes! (And don't want to pay M$ for the privilege of using their hardware ;) Regards, Ranjit.

by Modnogg

I Saw the Scratchamp driver for linus is now opensource. Do you think it's possible now to change the external soundcards in the scratchamp can be replaced in the driver by internal soundcards? grtz, Modnogg

Re: [linux-audio-dev] Echo Darla/Gina/Layla/... on Linux

by Ranjit Singh

Hi, I was wondering whether there'd been any progress on this? I have a Darla card, and would love to get it working under Linux. I have experience of assembler (since 1983) if that would be of any help.. Regards, Ranjit.

[linux-audio-dev] Anyone able to run Csound in Linux in real-time?

by ico＠fuse.net

Hi all, I've been messing with Csound recently in order to see whether csound can be used well in real-time settings. The problem is that I tried icsound and the other csound (forget the source) and neither were able to output anything in real-time. I've used -o devaudio flag, also -W (for wave) output, and while my scorefile finished without any errors, I got no sound out. If I try to do <csound call> > /dev/dsp I get garbage sound since the header is all screwed up by the verbose output of the csound process. I am using latest ALSA and I compiled csound from scratch and still no luck. So, I was wondering if anyone had any luck running it in real-time. P.S. I've been also having a terrible time trying to compile externals in the icsound (i.e. OSCext and others). I get a huge number of errors and am not sure where the problems is stemming from. Any help is greatly appreciated! Ico
